Here at VetteSport in Tennessee I prepped my first C8 for the Track. What a Bitch! We removed a front and rear pad for information and pictures. Flushed the brake fluid out to Castrol. Then, We weighed the car,Z51, came out to 3444 Lbs. Corner weights were 51.6% LF to RR. Track specs for Alignment are 3 degrees neg. camber front and 2.5 neg. rear. Slight toe in front and rear. 56.8% rear weight full of Fuel with 190 lb driver! I'll post some videos next week on You Tube as to what we did and how to do it. We still have to add 2 qts tranny fluid for track use. Air Intake box has to be removed to access top of Tranny fluid plug. All info I have learned will be shared. Stay Tuned. Jerry

What amount of brake fluid does it take?

I look forward to the YouTube video, I only planned on flushing the brake fluid to SRF then getting the alignment performed. Would you guys have a dealer do this or local indy shop?!

If you know and have a relationship with a high quality local ‘Race shop’, I’d have them do the brake flush and alignment for sure. Just make sure they have any specific tools necessary; (for instance I don’t know if the C8 needs the rear caster set like the C7’s do), and that they are aware that the brake flush needs to be done in a certain manner or you can drain the master cylinder pdq apparently.

I'll make a post on the C7 Performance section and see if there guys in LA that know of a good shop. I wasn't aware of upgrading the tranny fluid, did Chevy specify this?

The owners manual indicates that you add two additional liters/quarts of DCT fluid above the regular "full level" for "track events," with no need to lower the fluid between events for street use.

It’s a bummer the air box has to be removed to add fluid to the DCT, I really wanted a BMC air filter before removing the air box and it’s strange there isn’t an easier way to access it. I’m looking forward to the YouTube video

Hello, KOTYKB,
From personal experience I highly recommend the Green Filter. See why here:
This video shows dyno proof of K&N performance gains vs paper filters. Of course based on the above airflow videos, the Green filter would theoretically have equal or greater results:
@copjsd I'll have to check out the green filter, in my Porsches as well as a lot of people who track theirs, we all use BMC. I've tried to get in contact with them with no luck on development of a filter for the C8

Airbox only has to come off for the track over-fill where you add 2 quarts to the top factory assembly fill port. The normal fill port is on the side of the trans like the manuals Tremecs.
Yesterday we put the 2 quarts of fluid in the C8, however i forgot to take video when we rebled the brakes. Removal of the airbox is not difficult but time consuming mainly due to all the wiring looms attached to the box. A small bore funnel is needed to pour the fluid into the tranny. We had a Corvette Engineer at the shop with us as well and he said the weight was typical of what they see at the plant. 56.5% rear weight. Also when manually bleeding the brakes you must disconnect the negative battery terminal or it will throw a code and limit you to 62 mph. He said the reason 2 extra qts wasn't added at the factory was weight, cost, and decreased mileage. He also said at Milford ,the engineers would put the fluid down the tranny vent tube which is easily accessible on the passenger side forward of the air box. They must have pumped the fluid in with a tank. Interior trim and closeout panel removed.
I'm sorry... I know your background racing, but I question the calibration of your scales or the fuel load in the car. The published curb weight for these cars is over 3,600. I haven't seen anyone weigh a 1LT yet, but it seems it will be around 3,570.
Yes my scales could be off at this large weight. Said Engineer from the Corvette plant said it was consistent with their data. Maybe Published vs. actual is different. I report only data I see with my 2 eyes. The scales haven't let me down in Tech sheds but We always double checked weight Track To Track even at 3400Lb. after Race weight rules.
Dealer had the fluid and the know how so I paid the dealership mechanic to do mine at his house I gave this to mechanic and he said thanks ! Lol He said this needed to come off Picture he sent me I was told it took two hours start to finish
@svcjmoDo you leave your camber at the "track" setting for daily use too? I'm going to likely track the car every few months and drive it 10k miles a year. How are the driving dynamics for highway use with the track camber settings? Also did you post the youtube video by chance?
